ro which it appertains to make and use the same,

reference being had to the accompanying drawings, and to letters of `reference marked thereon,which.form a part of this specification.

My invention relates to hollow -bobbins or quills employed for holding yarn during the process ofl manufacturing textile products; audit consists, essentially, in a hollow bobbin adapted for use in loom-shuttleshaving in its exterior surface diagonally-disposed interzo seating grooves, and having holes extending transversely throughA the shell andcommunieating with the grooves.

Usually heretofore in the process of dyeing yarn or in bleachingit the practice has z5 been to unwind it from the bobbins-and form it into skeins-4 skeining it, as it is termedn which skeins are then subjected to the various operations necessary to produce the desired color. When the yarn has been thus treated 3o and dried, it is rewound upon bobbins, it then i being ready to beplaced in a shuttle of a loom.

An objection to the skeining of the yarn preparatory to thedyeingoperation is that it materially increases the cost of the manufactured product, not only by reasonv o f the time consumed in the operation, but also by producing an increased'percentage ofl Waste varn.

In order to obviate or at least greatly reduce the expense incident to the bleaching, dyeing, or coloring Vot yarn by such former method, it has been proposed heretofore to wind the unbleached or uncolored yarn upon perforated grooved Abobbins, which are next immersed-in or subjected to the dyeing liquid, the latter,

by means of'a suitable pump,being caused to pass through the perforations of the bobbin and throughoutthe mass of yarn wound thereon, the grooves affording-ducts for the.pas sage of the-coloring-matter and causing it'to 5o engage and permeate the entire interior portion of the; yarn lying adjacent to the barrel of the bobbin, the mass of liquid lying outside, Y at thisame time aecting the exterior of the woundyarn. Now yupon-establishing a circul'ation of the liquid it will pass through the yarn and bobbins and aftera short time com# pletely color it. VAfter removing the bobbins or cops of yarn from the action of the dyeing,- liquid and drying them Athey may be placed in a shuttle and used in a loom, &c.,' as usual. `The object of my invention is to provide au improved bobbin intended for use in the latter method of preparing the yarn, and which shall be so constructed as to lhold the load of' 65 yarn Wound thereon Well in placeand prevent the khocking oi of such load after the lled bobbin has been placed in the shuttle of a loom, andwhile the shuttle is being thrown from side to side in the loom. 7o

`My improved bobbins when filled with yarn may be very advantageously employed in mills Where the yarn is steamed before being Woven into cloth. Inorder to prevent the coloring-matter,` &c., from penetrating the I woodenbobbin or spool, I prefer to have the surface of them enameled both within land without. y

It will be seen that by reason of the grooves formed inthe surface of the yarn-retaining portion of the bobbins-there Will' be produced a series of small channels, along which the coloring liquid, steam, bleaching-chemicals, dsc., may flow to more readily engagelthe interior portion of the yarn and permeate it than would be, the. Oase if the yarn 'were wound upon a bobbin having a smooth surface, or even one provided. with holes only, and having the groovesomitted, andl also that the intersecting diagonal arrangement of 'the grooves, which vin practice will be se? cured by forming opposite spiral grooves. around the bobbin, provides 'for the passage of the bleaching ordyeiug liquid to allparts of the interior of the yarn-load upon the bobbin and the thorough permeation of the yarn-load, more completely distributing the liquid to the yarn, and at the same time such grooves provide a holding means whereby the mass of yarn upon the bobbin is prevented from moving endwise upon the lat'- ter under the iniuence of the shocks occur- Y ring during the operation of the shuttle. This ro holding of the yarn in place. is highly impor- Y tant, as will of course be understood by those skilled in the art of weaving. In the case of bobbins intended to be used in loom-shuttles and to have the yarn which is wound thereon bleached or dyed while still held thereby, it

becomes doubly necessary to provide means for preventi-ng the yarn-load from slipping endwise, inasmuch as during the treatment of the yarn thelatter, as a result of being first zo" wetted and then dried, becomes stretched, so

that the coils thereof no longer clasp the exterior surface ofthe bobbin as closely as when first' wound thereon. Y

In the appended drawings, Figure l is a 2 5 side elevation of a boblon provided with my improvement. Fig. 2 is a central longitudi' nal sectional view takenv on line x of Fig. 1, and Fig. 3 is atransverse sectional view taken on linemm of Fig. l.

V In the drawings, A designates my improved bobbin or spool as a whole and as made of wood or other suitable material. In some cases I find it desirable to make the yarn-retaining portion or barrel of metal, as tin, 3 5 copper, the. In an7 event the bobbins are hollow-that is to saytheyare provided with' a central longitudinal hole extending up into or entirely through them, therebyadapting the bobbins to be mounted on a spindle, as

4o usual. l

rEhe exterior surface of the barrel portion a.

'of thebobbinhas formed therein a series of shallow grooves b. These grooves extend longitudinally of the bobbin in the form of 1,5 spirals. As drawn, the-spirals are oppositely arranged and intersect each other at intervals. I sometimes further provide the bobioin with a series of short grooves arranged parallel with the bobbins axis, as shown. The spiral grooves act to eitectually retain the yarn-load in position upon the bobbin.

The barrel a of the bobbin is further provided with small holes c, cut transversely through the shell at convenient intervals and communicating with the grooves, asv clearly represented. When thus. grooved and. perforated, the yarn-load is uniformly acted upon -by the liquids during the bleaching or dyeing Y process.

By covering the entir'esurface with enamel the bobbin is Vpreserved from the actionof steam, 85e., during the treatment of the yarnload, thereby preventing the bobbin from splitting, warping, 'or checking.

In the drawings the grooves are represented as terminating intermediate of the ends of the bobbin. Itis, however, notessential that such limitation be strictly carried out, as it is obvious that the grooves may extend to the extreme ends without departing from the spirit of my invention.

l claim as my inventionl. A hollow bobbin adaptedfor use in loomshuttles, having in its exterior surface diago.

:daily-disposed intersecting grooves, and having holes extending transversely through the shell and communicating with the grooves.

2. Au enameled Lhollow bobbin adapted for use in loom-shuttles, havingvin its exterior surface diagonally disposed intersecting grooves, and having holes extending transwith the grooves.
